Subject: RE: [usb] Corrupted Ack during Last Burst In Transaction
Please read section 8.6.4 which specifically talks about ACK corruption.
It will lead to temporary loss of synchronization.

Subject: [usb] Corrupted Ack during Last Burst In Transaction
Sorry for poor English ;)
Host reads data (Bulk transactions) from USB device.
..
When host need to read last portion of data,
he send IN packet,
device send DATA packet,
host receives it with out error and send ACK packet
Question: How host can be sure,
that device received ACK packet without error?
For example, if host reads from FIFO (USB device),
how he can be sure, that he reads all data from it?
And FIFO become epmty !!!
